June 2017 extended the spell of “exceptional global warmth” that has now lasted since mid-2015, according to the latest analysis from the Europe Centre for Medium Range Weather Forecasting Copernicus Climate Change Service. Average surface air temperatures were the second hottest on record, after June 2016.

In addition to high temperatures, extreme weather affected many different parts of the world in June and early July. This summary is compiled by the WMO Secretariat based on reports from national meteorological and hydrological services.
